Figure 3. Alignments for deduced amino acids of HVR2s from Beijing HRSV-B strains and representative reference strains of identified HRSV-B genotypes.

Amino acid numbering is shown relative to prototype CH18537 (GenBank accession number M17213). Only Beijing strains with unique HVR2 sequences are included in the alignments. Identical residuals, stop codons and gaps are indicated by dots, asterisks and dashes, respectively. Genotype names, followed by the length of G proteins, are shown at the end of the sequences. The G protein length of Beijing strains are deduced from the full length of G protein, while the G protein length of reference strains are given according to prototype of A2. Potential N-glycosylation sites (NXT, where X is not proline) are indicated by gray shading. Different background colors are used to facilitate visualization of different genotypes.
